CAR Roer.

:Application vfiled December 13, 1926. vSerial No; 154,431.

My invent-ion relates to car rools and has for :its princlpal object to produce a simple and economical construction that `1s easy of application and lthat will :readily :adapt itsell to the distortions of' the car `body incident to service conditions. The invention consists in the parts `and inthe combinations and arrangements of' parts hereinafter described and claimed.

ln the' accompanying drawings, which form part of this specification and wherein like symbols refer to like partswherever they occur,k

Fig. 6 is a fragmentary'plan view of the ridge portion of a carline .of modified construction; and

F ig. 7 is a verticalcross-section on the line 7-7 in Fig. 6. f

The present roof comprises Z-bar side platesS that ares-connected by carlines 9 of substantially inverted channel-shapedsection with Aoutwardly projecting lateral base flanges 10 at the `bottoms of v`their sidewalls. The Z-bar side plates 8 :are preferably .arranged with their websgve'rtical and with their top flanges extendinginwardfly horizontally; and the eaves end portions 4of saidcarlines .'9 restflatwisepnjthe inwardly projecting top flanges 'of Asaid side plates .and have their la-terjal baseflanges 10 rigidly secured thereto byrive'ts 11.

Metal roof sheets 12 extend 'from eaves to eaves of the car between adjacent carlines and are of less width than the spaces `between the inverted channel-.shaped body `portions thereof. `Said roof sheets rare supported-at the eaves preferably on wooden `filler-strips 13j, vwhich extend from carline'to `carline and rest on and are rigidly secured to thetop flanges of the side plates by bolts 14. The root sheets are also supported between the ridge and the eaves, preferably byfmeans of purhns 15, which extend longitudinally of the oar beneath the oarlines andare bolted wor otherwise rigidly secured to `the lateral base flanges thereof. The roof sheets are provided at their eaves vends with depending flanges 16, which overhang and are spaced from the Webs of theside plates. The roof sheets are supported on the fille-r strips 13 and purl-ins 15 above the plane fof the base flanges of the cai-lines and have fupwardly offset side marginal portions 17 that are inclined upward-ly and terminatein .upstandf ing side `marginal seamflangfes 18 that extend from end to end otsaid sheets.

The roof sheets are loosely connectedalong their adjacent side margins by weatherproofying seam `covers :or caps 19 of substantially inverted channel-shaped section which strad? dle the oarlines 9 and the upstanding 'side marginal seam flanges 18 of adjacent sheets, the side `wallsof rsaid seam covers andsaid seam flanges being" normally spaced apart from end to end of the sheets. As shown in the drawing, the Webs of the inverted channel-shapedyseam covers 19 rest flatwise on the webs of the inverted channel-shaped car lines 9 and are rigidlysecured ,theretoat poi-nts adjacent to the ridge and eaves Vby rivets 20. The seam covers 19 yrare provided.

along the lower edges Yof their side walls with outwardly projecting :lateral "base :flanges 21 that conform to the slope of the upwardly 'offset side marginal portions 17 of the :rootl sheets and are arranged to rest `or bear llatwise on said portions, thereby holding said sheets down'on the oar. The eaves end portionsof the seam covers 19 `are provided with depending eaves flanges22, which overlap the openends :of the carlines 49 and the end portions of :the 1 depending eaves flanges 16 of adjacent .sheets and are `spaced away from said eaves flanges.

Running boards 23 extend longitudinally of the carat .therid'ge and :are supported on `the lateral top flanges fof Z-bar running board saddles .'24, whose rl'ateral base `flanges rest on lthe ridgeport'ions of the seam covers 1 19 and are rigidly secured in position by the rivets 2O that secure the ridge portions of said seam covers to the cai-lines i).

Riveted or otherwise rigidly secured to the under side ot' each roof sheet at the ridge is a stiflening member comprising a strip of sheet metal Q5, which extends transversely of the sheet with its end portions supported on the opposing base fianges of adjacent earlines and bent up beyond the side margins of the sheet to torni upstanding end lianges 2G. The stili'ening members are provided with longitudinal still'ening ribs 2T that. terminate short ot their end flanges QG. `The end flanges 26 oi" the sheet stiflfeners are bowed or curved outwardly from side to side to form convex surfaces QS at the ends ot' said members; and the portions of the side walls of the carlines located opposite the. convex ends of said sheet stilcners are longitudinally curved or bowed inwardly toward each other to form in the outside faces of said carlines concave depressions or sockets 29 adapted to receive the, ends ot said stifl'encrs. As shown in the drawings, the convex ends of the sti fliening members and the concave sockets ot the carlines have substantially the same radius o'l curvature and are curved in circular arcs described l" rom the centers ot the sheets.

In the modified construction illustrated in Figs. 6 and 7, the carline 9a is of full width at the ridge, and a pivot clip 3() of inverted channel-shaped section straddles the carlinc at the ridge and has its side flanges bowed inwardly to form curved recesses or sockets Q9 for the convex ends E28 of the sheet stillening members 25.

By the arrangement described, the socket connections between the sheet stifening members and the carlines enable the roof sheets to accommodate themselves automatically to the distortions ot the car body by forcing the sheets to pivot or slue about points located at their centers. The socket joints or connections between the opposing faces of adjacent carlines and the convex ends oi the sheet. stilleners serve to prevent bodily movement ot the sheets both longitudinally and transversely ot the car and thus normally maintain a proper clearance between the eaves flanges ot the sheets and the side plates and between the sides of the sheets and the seam covers and carlines. The sheet stiffening members rest on the opposing base tlanges of adjacent carlines and thus serve to support and stitien the sheets at the ridge. while the upturned end flanges of said members abut against the opposing sides of adjacent carlines and thus serve as struts or braces to maintain a proper .spacing of the carlines at the ridge.

The invention is not limited to the precise shapes and arrangements of parts shown and described. F61' instance, the radii ot the convex ends of the sheet stiffeners may be less than the radii of the concave sockets in the carlines; also, the radii of said concave sockets may be longer than the distance between the cent-ers ot' the sheets and said sockets.
